A method includes detecting a trigger condition, and in response to detecting the trigger condition, reducing a voltage applied to a graphics controller component of a memory controller. The reduction in voltage may cause the voltage to be reduced below a voltage level required to maintain context information...http://www.google.de/patents/US7222253?utm_source=gb-gplus-sharePatent US7222253 - Dynamic power control for reducing voltage level of graphics controller component of memory controller based on its degree of idleness
